Instrument Transformer :
  Metering Out Fit

SCOPE

M.O.F (Metering Out Fir) is used to measure the electrical power in combination with meters such as triple tariff watt hour meter, watt hour demand meter and var hour meter

FEATURES

  1. M.O.F is a precision class out fit and can be used after converting the current capacity changing tap.

  2. Long consistency and high reliability with simple design and easy construction.

  3. Good quality using of good material and parts

  4. Facilitating of installation and operation conveniently with minimized size and light weight.

  5. The type according to insulating material of M.O.F is as follows :

    1)
    Air insulation - The type of JWM 93-5 is air insulated, completely self-contained, mounted upon a hot dipped galvanized steel base-frame, factory assembled in a totally enclosed aesthetically acceptable cladding, vandal-proof and weather proof.

    2) Oil insulation - The type of JWM 9301, 2, 3 is oil immersion insulated, completely self-contained, mounted upon a hot dipped galvanized steel base-frame, factory assembled in a totally enclosed aesthetically acceptable cladding, vandal-proof and weather proof.

  6. If required by customer according to service condition (Weather, Fire, etc), we can manufacture the LF insulated instrument transformers instead of mineral oil.

LE - instrument transformer filled up with less flammable insulating fluid (silicone fluid) and insulation level of winding and LF is class H (insulation level or mineral oil is class A)

Class H insulation
   H -  Average temperature rise of winding/LF() is 95/80
   A -  Average temperature rise of winding/Oil() is 55/50

ATTENTION

Do not open the secondary circuit terminal of current transformer during M.O.F operation.
